Commercial Graphene Production // Allotropes and Applications

Күн бұрын

We're entering the graphene age. This video will include a primer on graphene, methods of commercial and industrial graphene production, allotropes of graphene, applications for graphene, and when we'll see it in products.
I explain bottom up and top down graphene production methods, the different types of graphene, and when we can expect to see the different types of graphene in products.
The types of graphene discussed are: Graphene Oxide (GO), Reduced Graphene Oxide (RGO), and Pristine Graphine. I also discuss Graphene films, Graphene Flakes (one layer graphene, two layer graphene, few layer graphene) and Nanoplatelets.
Talga Resources and Beeasy Graphene Company are discussed to provide examples.

Again you managed to explain a complex issue pretty easily. What people need to remember that, as Neil deGrasseTyson said many times, carbon has more ways to combine with itself and other elements than all other elements combined. And carbon is one of the most common elements in the universe after H, He and O. What may be missing from this video, and what you address in one of the next videos, is how a relatively small amount of, some form of graphene, enable other materials to be stronger and have a better conductivity then itself on its own.

That's a great quote by NDGT! Great question how so little can stretch so far: 1) Usually these things are done by weight. If you fill a 1 liter jar with graphene, it only holds 70g or so. So, even a few weight percent of graphene in a volume of a material has a massive impact throughout the volume. 2) It's so extreme in it's conductivity and strength. Combine 1 & 2 and that's pretty much the answer. 😃

The Limiting Factor Neal Stephenson wrote an SF book called The Diamond Age in 1995 where he explores a world where carbon based nanotechnology is ubiquitous. In this respect Diamond Age is comparable with the Graphene Age. The term Diamond Age was coined by Ralph Merkle who together with Eric Drexler popularized nanotechnology.

We’ve experimented with different conductors and played with photovoltaics and how photons excite the atoms to release their electrons. He gets it totally and very often comes back the next day with questions that I have to dig into in order to explain because the answers are beyond my current knowledge. Your video is exactly what I’ve needed to explain the basics of carbon to him. He will completely understand this now . Having only a high school background in these subjects I’ve had to spend my life learning this independently and content like yours is a bonanza for my 70+ year old mind to keep up with.

You mentioned that carbon could be made with less-structurally-sound larger rings. Makes me wonder about whether such rings could be formed "bespoke" into "far harder than diamond" repeating structures, that are closer to a "woven textile" in design, or high-carbon steel at a micro-scale. (I.e. With interlocking rings of carbons that, if weaker than c6 tiling by themselves, would be strong if they were linked together like chain-mail armor.) A larger version of this would be weaving together ultra-long SWNTs with each SWNT forming "a single thread, to be woven." This stuff is fun to think about. Of course, it was nearly all predicted by Drexler's "Engines of Creation." Edit: Sure enough, my memory was correct. All kinds of geometries are possible. Here's a white paper discussing them, with a graphic. It's interesting to imagine A long wire of SWNT running down the middle of a long stack of the hexagonal toroids. Would it be ultra-strong and ultra-tough? Would it carry current without breaking? Once ultra-long kilns exist, reality is going to get weird. Ideally, we all live long enough to put our brains on a mostly-carbon neuron substrate.

Once it's tethered, a simple gravity drop should/could pull it out like taffy. And by tube I mean literal in a sense, but whatever can step down the layers. If it can be tethered in this model as abstract as it is the strength alone should hold through the pull. Just have to figure out what the 'tube' could be.

Please do a piece expanding on this aspect, focussing on the work of The Graphene Council in the US and Manchester University’s GEIC (Graphene Engineering and Innovation Centre) in the U.K. And get to know Versarien, the real leader in FLG, the only one globally whose process has been yet been validated by The Graphene Council as scalable few-layer Graphene, as well as by the NGI in U.K. and also in China. Now collaborating with the likes of AECOM, Airbus and Rolls-Royce at the highest end of tech for Aerospace, Construction, 3D printing, textiles etc. With a very approachable CEO in Neill Ricketts, who has also just launched the first fully approved K95 Graphene enhanced anti-COVID face mask.
